Hospital Food Experience Questionnaire (HFEQ): Reliable, valid and predicts food intake in adult patients

Abstract

Background & aims: Low food intake is a primary contributor to iatrogenic hospital malnutrition and can be influenced by perceptions of poor food quality. Valid and reliable tools to assess the food experience of hospital patients are lacking. This study aimed to determine the internal reliability, convergent construct and predictive validity of the new Hospital Food Experience Questionnaire (HFEQ) and to methodically derive and test a shortened version of the questionnaire (HFEQ-sv).

Methods: Data from a multi-site study on 1087 patients from 16 Ontario hospitals were used. The HFEQ was developed to assess the importance of food (n = 6) and food-related (n = 10) traits using a 5-point Likert scale anchored by "not important" (1) and "very important" (5), and ratings of a single meal served (n = 7) using a 5-point Likert scale anchored by "very poor" (1) and "very good" (5). Food intake at the same meal was assessed using visual estimation (0%, 25%, 50%, 75%, 100%). Internal reliability was determined using Cronbach's alpha, and principal components analysis (PCA). Convergent validity was assessed using ordinal logistic regression with a single question on patients' overall meal quality rating. Cross validation was conducted in an attempt to shorten the questionnaire and binary logistic regression determined predictive validity with food intake.

Results: The HFEQ demonstrated good internal reliability (α = .86), and all but one of the questionnaire items clustered together in PCA, revealing 5 factors. Subscales and the total HFEQ demonstrated convergent validity, with the importance of food taste, choice, easy-to-open packaging, easy-to-eat food and local food provision, in addition to meal ratings of taste, appearance, texture, temperature and combination of food served being associated with the overall meal quality rating (p < .050). These items became the basis for the HFEQ-sv, which was found to independently predict food intake (LRT(42) = 142.17, p < .001).

Conclusions: The HFEQ is internally reliable, demonstrates convergent validity with the construct of meal quality and predicts food intake. The 11-item HFEQ-sv promotes feasibility. The HFEQ has potential to be used globally to benchmark and quantify the patient food experience in hospital, contributing to quality improvement strategies that will support food intake among patients.
